SUBMARINE BOAT.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed February 21, 1906. Serial No. 302,245.

To all whom, it may concern:

storage-and transmission means, may re-.

main submerged during an extensive period, in which the gasolene engineemployed to actuate the various electrical a pliances, may be operatedunder all con itions, and in which, by proper and economicaldistribution and circulation, the stored air may be employed to thegreatest advantage.

The benefits derived from the improvements herein described will beappreciated when it is observed that to prevent contamination of the airby the gases ejected from the engine, the electricity required tooperate the various contrivances in submarine boats now in use duringthe period of submergence, is supplied by batteries which are chargedwhile the boat is on the surface.

Recent tests have furthermore. .st Qblished the average length of theperiod of submergence to be approximately eight hours at the expirationof which time the boat has to be brought to the surface for the purposeof replenishing the air tanks.

I attain my objects by the system and mechanism illustrated in theaccompanying drawings, in the various views of which, like parts aresimilarly designated and in which,

Figure 1 :represents a vertical, longitudinal section through asubmarine boat, equipped in accordance with my improved system, Fig. 2ahorizontal, longitudinal section through the same, taken along a line22, Fig. 3, Fig. 3an enlarged cross section taken along the line 33,Fig. 1 and Fig. 4an enlarged sectional, fragmentary view of the variouselements comprised in my system of air-storage and trasnmission.

Referring to the drawings, 5 represents the cigar-shaped hull or shellof a submarine boat,

adaissto the interior of which may be had by means of a normallyhermetically closed hatch 6, opening in the upper surface of theconning-tower 7.

The vertical movements of the boat are controlled by the horizontalsubmerging screws 8, which are revolubly mounted inside verticaltransversely arranged conduits 9 and which are actuated by a motor 10,through instrumentality of a; longitudinally extending shaft 11. j

The boat may be propelled while upon or under t. -.e surface of theWater by four screwpropellers 12, which receive their rotary movementfrom the electric motors 13, while the steering apparatus of the vessel,consists of two horizontal, longitudinally extending planes 14,pivotally mounted on shafts 15, and controlled by means of hand wheels16.

The submerging, propelling and steering means have respectively beenmade subjects of separate applications for patent.

The interior of the boat is divided into a I centrally located engineroom 17 and the operating room 18, the floor 19 of which surrounds theformer.

The roof 20 of the engine room extends below the conningtower and formsthe floor which, in practice, is occupied by the operator and steersmenof the vessel. I

The electric switches and rheostats employed to control the movements ofthe various appliances and which together with the electricalconnections have been omitted from the drawings, are to this endpreferably located in the conning-tower.

Engine room 17 contains the gasolene engine 21 and the therewith('Jperatively .connected dynamo 22, by which the various motors employedin propelling and governing the boat are energized.

The interior of the boat is furthermore divided by means of bulkheads 23and 24 into two end compartments 25, located respectively at the sternand prow of the boat and two thereto adjoining compartments 26.

Chambers 25 are intended for the storage of the gasolene required forthe operation of the engine and are connected. with the engine room bymeans of pipes 27, while the adjoining chambers 26 are designed tocontain the foul air exhausted from the operating and engine rooms andwhich being compressed therein, may subsequently be employed to operatethe torpedo and dynamite guns, the position of which is indicated inbroken lines 28, Fig. 1.

The space 29 surrounding the engine room below floor 19 is employed tostore the compressed air required to supply the vital oxygen to theoccupants of the operating and Engine rooms during submergence of theoat.

Compartment 29 is supplied with compressed air while the boat is on thesurface of the water by means of an air compressor 31 operated by amotor 34 and connected with the said compartment by the eduction pipe32-, while the induction pipe 33 extends inside the conning-tower. Whenthe air compartment is filled, valve 32 in pipe 32 is closed and theboat is ready to be submerged.

The operating room 18 is, during submergence of the vessel, suppliedwith vital air by means of the valve-controlled inletpipes 30, whichextend from compartment 29 through floor 19, while the foul or impureair is exhausted from the upper portion of the said room by means of thebefore named compressor 31 and the induction pipe 33 and led into thelower portion of the engine room 17 by the auxiliary eduction pipe 34,the valve 34 of which, was closed while compartment 29 was being filled.

The air which rises in the upper portion. of the engine room, beingunsuited for further use in the living compartments, is exhaustedthrough a pipe 35 by means of a compressor 36 and conducted into one ofthe foul air chambers 26 by the eduction pipe 37. The compressor isactuated through instrumentality of an electric motor 38.

The two foul air compartments 26 are connected by a pipe 39, a branch ofwhich,

' leads to the conning-tower 7.

The upper extremity of pipe 40 is provided with a cross pipe 41, whichhas an outletvalve 42 and a safety-valve 43. The latter guards againstover-compression of the air in the foul air tanks, while the formerpermits the discharge of the impure air when the boat has returned tothe surface.

, The gases or vapors, which duringthe op eration of the gasolene engineare constantly exhausted therefrom, are connected through a pipe 44 intoa condenser or purifier 45 in which solid and other impurities containedin the gases are separated therefrom and from which the vapors are ledthrough a pipe 47 into the expansion and storing tank 46. Theaccumulated gases are exhausted from tank 46 through a pipe 47 by meansof a compressor 48, which discharges into the foul air tanks 26 througha pipe 49. The compressor is actuated by the electric motor 50.

Tank 46, being sufficiently large will, together with check valves 51and 52, prevent reaction of the accumulated gases on the engine.

Having thus described my invention what I claim is 1. In a submarineboat, a normally water tight shell comprising an operating room, freshair and impure-airchambers, means to compress air in the fresh airchamber, means to conduct air therefrom into the operating room, andmeans to exhaust the impure air from the latter into the foul airchamber.
